Paperboard bottle carrier
Abstract
A bottle carrier is formed of one or more panels of paperboard
and includes a plurality of bottle neck receiving openings. The
periphery of each opening is defined by the tips of a plurality of
radially extending fingers, the tips engaging beneath a portion of
an abutment associated with each bottle neck. Each finger is bent
upwardly at about 45 degrees after insertion of a bottle into a
respective opening. Each radial finger is provided at its widest
portion with a base slit extending thouugh the paperboard. Another
and intermediate slit is located about half way along the length of
each finger, the intermediate slit also extending through the
paperboard. These slits are of lesser width than that of their
respective fingers and are parallel to each other and are at right
angles to the length of the finger. The base slit permits bending
of each finger upwardly upon bottle insertion, while the
intermediate slit facilitates removal of each bottle from its
respective opening.

Claims
We claim:
1. A bottle carrier formed from a unitary paperboard panel, said
panel having at least one bottle neck receiving opening, said
opening having a plurality of cut lines extending through said
panel and extending radially outwardly from said opening to thereby
define a plurality of radially extending fingers, tips of said
radially extending fingers terminating at said opening, each said

Description
BACKGROUND OF THE INVENTION
This invention relates to bottle carriers of the type fashioned
from one or more planar sheets of paperboard, the sheet having a
plurality of openings for receiving respective bottles. Each bottle
receiving opening has a plurality of radially outwardly extending
fingers defined by cuts through the paperboard. In general, such
carriers have been used largely for cans. Examples of constructions
of this general type are shown in U.S. Pat. No. 3,834,750 issued to
Gauntlett, U.S. Pat. No. 3,156,358 issued to Randrup, and U.S. Pat.
No. 5,125,506 issued to Galbierz et al.
While planar paperboard bottle carriers have been widely employed
for carrying cans, such as soft drink cans or the like, they have
not been widely accepted for carrying plastic bottles having
integral annular flanges around their necks. Generally, the annular
flanges associated with bottles, or the screw caps on bottles, are
so much larger in diameter than the diameter of the openings in the
planar carrier that it is difficult to remove a bottle from its
respective opening.
SUMMARY OF THE INVENTION
According to the practice of this invention, each of the radially
extending fingers of each bottle opening is provided with two
parallel slits extending through the paperboard. One slit is termed
the base slit and is located at the widest part or base of the
finger and the other or intermediate slit is located about half way
along the finger length. The slits are at right angles to the
longitudinal axis of each finger. The base slit permits upward
bending of each finger at its base, while the intermediate slit is
relatively easily broken or fractured when a respective bottle is
tilted and twisted and pulled downwardly to remove it from the
carrier.
This invention is related to the inventions described in copending
application filed Jun. 30, 1994 by Linda A. Bernstein entitled
Paperboad Bottle Carrier, Ser. No. 08/269,328 hereby incorporated
by reference.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a plan view of a unitary blank of paperboard or other
stiff, foldable, and resilient sheet material from which the bottle
carrier of this invention is fashioned.
FIG. 2 is a view similar to FIG. 1 and shows the blank of FIG. 1
after it has been folded about two parallel fold lines and glued,
ready to be loaded with bottles.
FIG. 3 is a view taken along section 3--3 of FIG. 2 and illustrates
plastic bottles inserted into the carrier.
DETAILED DESCRIPTION OF THE INVENTION
Referring now to FIG. 1 of the drawings, the numeral 10 denotes
generally a unitary blank of paperboard or other stiff, foldable
and resilient sheet material such as 57#/69# Kraft paperboard,
typically of a caliper 0.030 to 0.032 inches. Blank 10 is generally
rectangular and is mirror symmetrical to the left and right with
respect to a vertical or longitudinal axis 12. Central panel 14 is
provided at its center with two trap door type flaps 16 defined by
a central cut 18 through the paperboard and collinear with axis 12,
two parallel cuts 20 through the paperboard, and two parallel score
or fold lines 22. Each quadrant of panel 14 is provided with a
bottle receiving opening 36 whose periphery is defined by the
radially innermost tips of radial fingers made by radial slits 38
extending through the paperboard. The base or widest portion of
each finger is provided with a base slit 40. Another and
intermediate slit 42 is located about half way along the length of
each radial finger 44, with slits 40 and 42 being parallel to each
other, both extending through the paperboard, and located midway of
the width of a respective radial finger. A typical dimension of
panel 14 is 5.625 inches on each side, as from scores 28 to 30, and
a typical length of slits 40 and 42 is 0.125 inches. Openings 32
are typically of 1.8125 inches in diameter. Edge notches 27 in end
panels 26 and 28 permit flaps 16 to swing downwardly, as will be
explained.
Referring now to FIG. 2, the blank of FIG. 1 has been folded about
fold lines 28 and 30, with panels 26 and 28 glued against the
bottom surface of panel 14. Trap door flaps 16 may now be bent
down, or may be bent down by the consumer at the point of purchase.
Notches 27 receive flaps 16, permitting the latter to bend down
beneath the plane of panels 26 and 28. The corners of the central
finger opening defined by flaps 16 may be curved. Openings 32 of
panels 26 and 28 are coaxial with respective bottle openings 36.
Panels 26 and 28 are seen to reinforce upper panel 14.
FIG. 3 illustrates plastic bottles 52, each typically formed by
blow molding from polyethylene terephthalate (PET), placed or
loaded in the carrier. Each bottle, typically, is provided with a
screw cap 54, a neck 56 and an enlarged and integral ring 58 around
its neck. For loading, the carrier is moved downwardly relative to
the bottles, with each bottle upper portion passing upwardly
relative to the plane of panel 14. The extent of the motion is such
that upon completion of the loading, the tips of radial fingers 44
engage the bottom of a respective ring 58. This relation is
maintained by the weight of the bottles, with the fingers 44 being
under lengthwise compression. The carrier is carried by the
purchaser inserting his fingers into the opening defined by panels
16. Each radial finger is slanted about 45 degrees form the plane
of panel 14. While shown as at right angles to the length of each
finger 44, slits 40 and 42 may be slanted so as to be at an angle
with respect to the longitudinal axis 37 of each radial finger.
Further, the slits 40 and 42 need not be parallel to each other. It
will be noted that the diameter of caps 54 is greater than the
diameter of bottle openings 36, but less than the spacing between
diametrically opposite pairs of base slits 40 of any opening
36.
When the consumer desires to disengage a bottle from the carrier,
the bottle is grasped, tilted and twisted and pulled downwardly.
These motions result in a fracture of several of the associated
radial fingers 44 at the region of intermediate slits 42, thus
facilitating bottle removal.
In the event that a particular bottle design does not include ring
or flange 58 on its neck, the tips of fingers 44 would then abut
either the lower rim of cap 54 or would abut the bottoms of the
screw threads (not illustrated) on the top of the bottle neck.
According to the invention, the exact form of the abutment
associated with each bottle neck 56 and engaged by the free ends or
tips of fingers 44, namely, ring 58, or the bottom of cap 54, or
the bottom of the screw threads, is not critical.
The number of radial fingers 44, the extent of radial cuts 38, and
the number of openings 36 may all be varied for particular bottle
weights and designs. Further, it will be apparent that reinforcing
panels 26 and 28 may be omitted if the thickness or stiffnes of
panel 14 is increased. It will be observed that the length of slits
40 and 42 is about one third of the width of any radial finger 44
at the relative locations of the slits, but this proportion may be
varied. The length of slits 40 must be sufficient to facilitate
bending at the finger bases, while the length of slits 42 must be
sufficient to permit fracture in their regions.
Geometrical terms of orientation, such as upper, lower and the
like, are used to facilitate the description and are not intended
as limiting.
